I'm using both blood purifier and magnetic pulser and have great results. I tend to be using more the magnetic pulser though, the blood purifier I keep forgetting to use. Only when I feel I need it then I wrap it around my hand/wrist.
Magnetic pulser gets you really feel all that is unwanted in your body - if you were not aware of it before, then during the treatment you KNOW what's there for sure.
Also, the blood purifier clears the microfilaria from the blood and oncosphere stages of Tapeworms or any other microscopic parasites residing in the blood, that's why I think it's a great supporting equipment to use when you're trying to clear filarial worms or tapeworms.
